The 2018 Infiniti QX80 is a full-size luxury SUV, part of the second generation introduced in 2011 (originally as the QX56, rebranded QX80 in 2014) with a significant refresh for the 2018 model year. It boasts a bold, commanding body-on-frame design, offering seating for up to eight. Key trims include the Base and the Limited. New pricing typically ranged from around $65,000 to over $80,000. It stands out for its plush interior, powerful V8 engine, and impressive towing capability, making it popular among large families and those seeking opulent comfort.
The Good

The 2018 Infiniti QX80 offers a potent V8 engine for strong performance and towing, appealing to practical needs. Its exceptionally comfortable and spacious interior, coupled with a commanding presence, provides an emotional sense of luxury and security. While not class-leading in efficiency, it delivers a robust and reliable luxury experience with a distinct design that stands out.

The Bad

Known weaknesses of the 2018 Infiniti QX80 include its relatively poor fuel economy, cumbersome handling due to its large size, and dated infotainment system compared to rivals. Some find its exterior styling polarizing, and its resale value can depreciate quicker than some competitors. Braking performance has also been noted as needing improvement.

2018 Infiniti QX80: Quick Overview

  • Engine: The 2018 Infiniti QX80 is powered by a single engine option across all trims: a 5.6-liter DOHC 32-valve V8 engine. This naturally aspirated powerhouse provides robust performance for its size.

  • Horsepower: This V8 engine generates a strong 400 horsepower and 413 lb-ft of torque, ensuring confident acceleration and ample power for various driving conditions, including highway merging and towing.

  • Transmission: Power is routed through a smooth-shifting 7-speed automatic transmission.

  • Drive Type: Available in rear-wheel drive (RWD) as standard, with an optional advanced All-Mode 4WD system featuring Auto, 4H, and 4L settings.

  • Fuel Economy: Given its size and powerful V8 engine, fuel economy is not a strong suit. EPA estimates are typically around 14 MPG city, 20 MPG highway, and 16 MPG combined for RWD models, and 13 MPG city, 19 MPG highway, and 15 MPG combined for 4WD models.

  • 0-60 MPH: The 2018 QX80 can accelerate from 0 to 60 mph in approximately 6.2 seconds, which is quite brisk for a vehicle of its stature.

  • Towing Capacity: A significant advantage for the QX80 is its impressive towing capability, rated at up to 8,500 pounds when properly equipped, making it highly capable for hauling boats, trailers, or campers.

  • Trim-Level Features: The 2018 QX80 was primarily offered in two main configurations: the standard QX80 and the QX80 Limited. The standard model (available in RWD or 4WD) came generously equipped with features like 20-inch alloy wheels, tri-zone automatic climate control, a 13-speaker Bose audio system, an 8-inch touchscreen infotainment system, leather upholstery, heated front seats, navigation, and a power liftgate. Optional packages added things like larger 22-inch wheels, a Hydraulic Body Motion Control (HBMC) system for improved ride and handling, a theater package with dual 8-inch screens for rear passengers, and a Driver Assistance Package. The top-tier QX80 Limited trim built upon these features, offering exclusive dark chrome accents, unique 22-inch dark machine-finished alloy wheels, satin chrome exterior trim, a semi-aniline leather-appointed interior with unique quilting, open-pore ash wood trim, heated and cooled front seats, heated second-row seats, a premium audio system, and a comprehensive suite of advanced driver-assistance systems as standard.

Analysis

What Problems Does the 2018 Infiniti QX80 Have?

The 2018 Infiniti QX80, while generally robust, has had a few frequently reported problems and long-term reliability concerns, alongside a couple of recalls. One recurring issue owners often mention relates to the braking system. Some owners report premature wear of brake pads and rotors, or a "soft" brake pedal feel, requiring more frequent maintenance than expected. While not a universal complaint, it's a consistent theme in some ownership circles. The infotainment system, despite being updated for 2018, can feel dated in terms of responsiveness and interface compared to more modern rivals, and some users have reported occasional glitches or freezing. Another area to watch, particularly on models equipped with the optional Hydraulic Body Motion Control (HBMC) system, is potential fluid leaks or component issues over time. While HBMC greatly enhances ride and handling, its complexity can lead to costly repairs if issues arise with the hydraulic lines or actuators. The power liftgate mechanism can also sometimes exhibit intermittent issues. Owners have occasionally reported problems with sensors, leading to dashboard warning lights, though these are often minor electrical gremlins rather than major mechanical failures.

Regarding recalls for the 2018 model year, two notable recalls were issued. One recall (NHTSA Campaign Number 18V556000) involved the potential for a fire from an aftermarket floor mat becoming trapped under the accelerator pedal, a concern for various Nissan/Infiniti models. Another recall (NHTSA Campaign Number 19V388000) addressed the Intelligent Key system, where the key might not be detected as being inside the vehicle upon opening the door, potentially allowing the vehicle to be operated without the key present, which could lead to theft or unintended movement if the driver exits with the key while the engine is running. These recalls were addressed by dealerships. Long-term reliability is generally considered good for the powertrain, but owners should anticipate higher maintenance costs compared to non-luxury vehicles and be vigilant about potential brake wear, electrical sensor issues, and the condition of the HBMC system if present.

How long will the 2018 Infiniti QX80 last?

With proper maintenance, the 2018 Infiniti QX80 is capable of delivering a long service life, often reaching 150,000 to 200,000 miles or more over 10 to 15 years. Its robust 5.6L V8 engine and body-on-frame construction are known for durability. Owners who adhere to the recommended service schedule for oil changes, fluid checks, and timely part replacements generally experience strong long-term performance.

However, certain components can become weaknesses over time. The aforementioned brake wear can continue, and the complex infotainment system might show its age with slower performance or occasional software issues. Suspension components, especially if equipped with HBMC, can be expensive to repair as the vehicle ages. Electrical sensors and wiring can also become more prone to issues. Consistent maintenance is key to mitigating these potential weaknesses and maximizing its lifespan.

What Technology & Safety Features are Included?

The 2018 Infiniti QX80 offers a substantial array of built-in tech, entertainment, and safety features designed for luxury and convenience, although some aspects felt a bit behind newer rivals even at its launch. Standard tech includes an 8-inch color touchscreen infotainment system with Infiniti InTouch, offering navigation, voice recognition, and a 13-speaker Bose premium audio system. Bluetooth phone and audio streaming, a USB port, and satellite radio are also standard. The system controls are a combination of touchscreen inputs and physical buttons and knobs, which some users appreciate for ease of use while driving.

For entertainment, a standard rear-seat entertainment system with dual 8-inch screens, wireless headphones, and a remote was offered as part of the Theater Package, providing excellent distraction for rear passengers on long journeys.

Driver-assistance and safety features were a significant focus of the 2018 refresh, with many now standard or widely available. Standard safety equipment includes a rearview camera, front and rear parking sensors, and a surround-view camera system with moving object detection. Optional, or standard on higher trims like the Limited, were advanced features such as intelligent cruise control, forward emergency braking with pedestrian detection, lane departure warning and prevention, blind spot warning and intervention, distance control assist, and adaptive front lighting with auto-leveling headlights. These systems work together to enhance driver awareness and mitigate potential collisions.

Regarding crash-test ratings, the 2018 Infiniti QX80 did not undergo testing by the National Highway Traffic Safety Administration (NHTSA) or the Insurance Institute for Highway Safety (IIHS) at the time of its release, which is common for many luxury, low-volume vehicles in its class. However, its strong body-on-frame construction, comprehensive airbag system (front, side-impact, and roof-mounted curtain airbags), and advanced safety aids provide a high level of passive and active safety for occupants.

2018 Infiniti QX80 Prices and Market Value

When new, the 2018 Infiniti QX80 had a starting MSRP of approximately $64,750 for the RWD model, with the 4WD version beginning around $67,850. The top-tier Limited trim could push prices well over $80,000.

In the current used market (as of late 2023/early 2024), prices for a 2018 QX80 typically range from $25,000 to $40,000, depending heavily on mileage, condition, trim level, and optional features. Models with lower mileage and the desirable Limited trim will command higher prices.

Depreciation for the QX80 is fairly significant, similar to many large luxury SUVs. It tends to lose a substantial portion of its value in the first few years. Factors affecting its resale value include its relatively poor fuel economy, which can deter some buyers, and the rapid advancement of technology in newer vehicles, making its infotainment system feel dated. Brand perception, while strong, isn't as universally lauded as some German competitors. High mileage, signs of wear and tear, and a lack of detailed service history will further depress its value. Conversely, well-maintained examples with complete service records and desirable packages hold their value better.

2018 Infiniti QX80 Cost of Ownership

Long-term ownership of the 2018 Infiniti QX80 is generally on the costlier side for a luxury SUV. Insurance premiums tend to be higher due to its luxury status, repair costs, and performance capabilities. Fuel costs are significant; with its V8 engine and poor fuel economy (13-16 MPG combined), expect frequent trips to the gas pump, especially with premium fuel often recommended.

Maintenance is standard for a luxury vehicle but can be pricey, particularly at Infiniti dealerships. Routine services are more expensive than for a mainstream vehicle. Repairs, when needed, can be quite costly for parts and labor, especially for specialized components like the HBMC system. Overall, it's a luxurious, capable vehicle, but not an economical choice for long-term ownership; prospective buyers should budget accordingly for its running costs.

2018 Infiniti QX80 Insurance

Insurance for a 2018 Infiniti QX80 is moderately priced, reflecting its status as a Sport Utility Vehicle with strong safety ratings and
reasonable repair costs.

How Does the 2018 Infiniti QX80 Compare to Other Sport Utility Vehicle?

The 2018 Infiniti QX80 competes in a fiercely contested segment of full-size luxury SUVs, primarily against vehicles like the Cadillac Escalade, Lexus LX 570, Mercedes-Benz GLS, and Lincoln Navigator.

In terms of Performance, the QX80's 400-hp V8 is strong, offering comparable power to the Lexus LX 570's 383-hp V8 and respectable acceleration. However, the Cadillac Escalade and Lincoln Navigator often boast even more powerful V8 or twin-turbo V6 engines, providing slightly quicker acceleration and sometimes better efficiency. The Mercedes-Benz GLS offers a range of engines, including more powerful AMG variants, often surpassing the QX80. The QX80's towing capacity of 8,500 lbs is competitive, often matching or exceeding rivals like the LX 570.

Regarding Features, the QX80 offers a plush interior with standard leather, navigation, and a Bose audio system. Its surround-view camera is excellent. However, its infotainment system, while updated for 2018, felt less modern and intuitive than the CUE system in the Escalade, the SYNC system in the Navigator, or the MBUX in the GLS. The QX80 excels in ride comfort, particularly with the optional Hydraulic Body Motion Control, which helps mitigate body roll. Its interior space is ample, but the third row can be tighter than in the Navigator or Escalade ESV.

Reliability for the QX80 is generally considered good, especially for the powertrain, aligning with its Nissan Patrol roots. It often holds up well over time, similar to the Lexus LX 570 which is renowned for bulletproof reliability. The American rivals like Escalade and Navigator also have solid reliability but can have their own quirks. Mercedes-Benz, while luxurious, can sometimes have higher repair costs.

For Price, the QX80 often presented a strong value proposition when new, typically undercutting similarly equipped Escalades, Navigators, and especially the pricier Lexus LX 570 and Mercedes-Benz GLS. This trend continues in the used market, where a QX80 often represents a more affordable entry into the full-size luxury SUV segment.

Similar Alternatives:
  • Lexus LX 570: For paramount reliability and off-road capability, though with higher price and older tech.
  • Cadillac Escalade: For bold styling, more powerful engine options, and a more integrated infotainment experience.
  • Lincoln Navigator: For a more modern interior, superior technology, and excellent passenger comfort, especially in the third row, but potentially at a higher price point.

Final Verdict: Is the 2018 Infiniti QX80 a Good Sport Utility Vehicle?

The 2018 Infiniti QX80 is ideal for buyers seeking a spacious, comfortable, and powerful full-size luxury SUV with strong towing capabilities, but without the premium price tag of some German or even domestic rivals. It suits large families needing three rows of seating and those who appreciate a commanding road presence and a well-appointed, if somewhat traditional, interior.

Is it worth buying? Absolutely, especially as a used vehicle. Its significant depreciation makes it an excellent value on the pre-owned market. Buying used allows you to get a lot of luxury, power, and utility for a considerably lower price than new. Look for models with lower mileage and a complete service history to mitigate potential long-term issues.

For optimal comfort and features, consider a model equipped with the Driver Assistance Package and, if you prioritize handling, the Hydraulic Body Motion Control system. The Limited trim offers an even more opulent experience. It's a solid choice for those prioritizing space and power over cutting-edge tech or class-leading fuel efficiency, provided you budget for its higher running costs.
